My invention relates to guiding 1 mecha- 1 nism that will deliver rolled sheets to a roll-- ing mill, or from one mill to another. .The ob ect of my invention is to provlde means for deliverin 'the sheets in such a manner b that the sheets'will .enter the mill' squarely, i. e., so that the axis of the sheets will at ways be substantially perpendicular to the axis of the rolls, whereby skewed ends are prevented from forming while the sheets are passing through the mill. e

It is another object of my'invention to p-rovidea fixed side guide for a sheet against which the sheet will be held by a positive mechanical means while passing from one mill to another. o Still another object of'my invention is to provide a means for holding the sheet in contact with the fixed guide, which means will adjust itself forany irregularities occuring along the edge of the sheet;

A further object of my invention is to provide a resilient pressure device for holding' the sheet against a fixed guide in a line perpendicular to the axis of the mills. v

Another object of my invention in one aspect is the. provision of driving means for the said pressure means, so that the sheets do not tend to bind, warp, or stick inthe 3o guides.

These and other objects of my invention which will he pointed out hereinafter or will be apparent to one skilled in the art upon reading these specifications, I accomplish by that certain construction and arrangement of parts or which I shall no-w describe an exemplary embodiment and a modification, reference being had'to the drawings which accompany these specifications.

I have shown two types of drums: for holding the sheets in proper alignment with relation to the rolls of the'mill. The do'u'ble drum. type as illustrated in Figures 1,2, 3"

tops 501? these chains extend "above the legs Figure 6, and are guided by means of-the sheaves 9 fixed'to an idler shaft 10 rotative'ly mounted" in the bearings :11 on the side frames of the conveyor.

One of the chains ;):a.sses:0ver a sprocket 12"- on a shaft 13 which is mounted in ahearing 14- on the side frame-of the conveyor. This shaft is heldfrom lateral thrust by'means elev a/tio'n of spring drum holding means, together with the conveyor andsideguide, with part's' in section; "Figure 5 is. a side'elevation' of a single I have shown a chain conveyor 1' having a" framework 2, which is used to [del ve sheets into. a mill or between two" mills.

hold 'thesheet of metal against a fixed side: '7 guide 16. The surface 16a of this guide is in a lineperpendicular to the millsandisthe means for keeping the sheet in proper align 'ment While passing to and entering between the rolls and 68 of the mills (see-Fig.

The other end 18 of-the shaft 13" is rotative- 1y mounted in a bearing" 19' which is part of line a of a collar 15 and the sprocket :12. It is the i main drive shaft for the pressuredrums-thatthe drum supporting bracket 20. There is a key slot 21 in this shaft in which a key 21, fixed in a bevel gear 22, is free to slide. Thls arrangement permits the movement of the bracket toward or away from the frame of the conveyor while keeping a positive driving relation between the shaft 13 and the bevel gear 22.

The bevel gear'22 meshes with and drives another bevel gear 23and alsoa vertical shaft 24, to which the said gear is attached;

v This shaft 24 is rotatively mounted in a bearing 25, also part of the drum supporting bracket. r v

The lower half 26 of a saw tooth clutch is fixed to the shaft 24 and drives the drum 27 through another'half 28. This clutch arrangement is provided to allowslippage between the pressure drum drive and the conveyor chain if-a sheet should become jammed betweenthe'fixediguide and the surface 29 of the drum.

My single drum arrangement consists ofa hub 30 which is rotatively mounted on the shaft 24 and is driven by the ratchet clutch as has been explained. The outerring31 of this drum is supported on the hub 310: by means of conical spring spokes 32, which are free to expand and contract when a sheet pushes against the surface 29. This ring has a flange 33' that supports the extending edge 34 of a sheet of metal in contact with it.

Normally, the drum will be positioned so as to be in contact with slight pressure againstv the edge of a sheet of metal. If there are any irregularities, the drum will follow them because of the action of the-springs, and thereby keep the sheet in contact With the guide 16. V

v In order to move the. drum into contact with a sheet, i. e. to set the device for guiding a new size of sheet, I have provided a screw 35,0ncend 36 being rotatively mounted in a bearing 37 fixed to the side frame of the con-' veyor, andthe .otherend 38 also rotatively mounted in another bearing 39 fixed to-an- I beam 40.: Thescrew 35 is kept from lateral movement by means of the thrust collars 41,

and may berotated by means of a handle placed on its squared end 42'. The screw operates in the threaded boss 43v of the drum supporting bracket, and thereby may be caused to move the bracket;

Extending from the sides of the threaded boss are wings 44 which are free to slidein I the channels 45 which guide-the drum supthe drum shown in section is provided with springs, as shown in Figure 4, the view in Figure 1 being at right angles to the springs. In the two-drum type, however, I have provided a supporting plate 46, which is rotatively mounted upon the shaft 24, and supports two drums 47 and 47 a, and gears to be described. I g

A spur gear 48 is keyed to the shaft 24, and

meshes with two idler spur gears 49 and 4960.

These in turn drive two additional spur gears 50 and 50a arranged to drive the two drums in the same direction (clockwise in the figures). The gears 49 and 49a are rotatively mounted'on studs '51 and 51a upon the'supporting. plate 4 6. The gears 50 and 50a are keyed to sleeves 52 which are 'rotatively mounted on studs 53 on the supporting plate.

The sleeves in turn are fixedly mounted in the hubs 54 of the drums and support the outer rin of the drums throu h s rin s okes. as

previously described.

Extending from the supporting plate is an arm 55 which has an upwardly extending supporting bracket 20. This arm is stationary and does not move with the supporting plate 46. A stud 60 passes through holes 61 in the spring plates and is held in a fixed posi- In order to regtion by the nuts 62and 62a. ulate the tension of the springs, I have provided threads 63 and 63a for nuts 64 and 6464 which screw against the springs and hold them in the desired compressed condition.

The normal setting of the supporting plate 46 is such that the forward drum 47 is somewhat furtheraway from the guide 16 than the rear drum 47 a. When a sheet 7 has come through the rolls, 65, it will be picked up by the conveyor 3 and carried toward rolls 68, possibly somewhat askew. The forward drum 4'Z will-engagethe sheet end first and will move it over toward the guide 16, at least to a position where it may be engaged by the rear drum 47a and resiliently pressed with its edge squared against the guide 16. Thus, a

proper automatic feeding of the sheet into the rolls 68 is ensured.

Various modifications may be made in my invention without departing from the spirit thereof.

I Having thus described my invention, what I claim as new and desire to secure by Let i151 ters Patent, is 2- 1.
